When I first met Laura she had a terrible sense of smell. It worried me a bit. Diminishing sense of smell can be an early indicator for Alzheimer’s. But since Laura has been on the Gerson diet, her nose is now so sensitive it’s like a super power. If I so much as pull a herb out of the fridge, she bounds over to sniff it. “Mmmmmmm – how is it your food always smells so much better than mine?” she sighs. Carrot juice and porridge aren’t nearly as aromatic.
